The UV nail polishes generally have some kind of acrylate. Every time you come into contact with uncured acrylates, there is a chance of developing an allergy to it, which means that the use of medical acrylates becomes much more dangerous if not impossible.

My chemistry teacher once made salmiak as a demonstration. The only experiment we were ever allowed to taste and quite cool to look at too.

No way he didn’t know what het was doing. He hesitates before he does it the first time, then when he get’s a positive reaction he does it the second time. This was deliberate and from what I can see many people in the the US are underreacting to it big time.

As someone born in 2000: No cause that day will not come.
